One astronomical method used that provided an insight about the universe is the LIGO (the Laser Interferometer Gravitational Wave Observatory). This method helps us detect gravitational waves emitted by astronomical bodies. The finding of gravitational waves will lead into understanding the behavior of other bodies that we did not know exist. The consequences are; one, we can measure the activity between two bodies in orbit in the universe, two, scientist can estimate the merging of two bodies in the universe every 15 minutes by using.
